Q: I want to run these tires with deep section carbon rims. Do they require Vittoria removable red valves or conventional valve extenders?

A: Any valve extender will work.

I switched from the Continental GP 4000's 3 years ago and haven't looked back! Whether you buy the tubular or clincher version, they have one of the lowest rolling resistance on the market, and corner better than any other tire I have tried on the market right now. Need something tougher? Go with the Vittoria Pave tires. Same tread pattern, but tougher for rougher roads. Need something lighter for a hilly race? Go with the Corsa Evo SC's. I tend to flat the SC's more, but they are light and fast.
